Appears in Driving Test?

Roundabout navigation is a fundamental assessment component in both theory and practical tests.

Written questions extensively cover lane selection, priority rules, signaling requirements, and appropriate speeds.

You must know that traffic on the roundabout has priority.

Practical tests include multiple roundabout types.

Examiners assess approach speed (should be 30-40 km/h), correct lane selection based on intended exit, observation for traffic from the right, smooth entry when safe, correct positioning while circulating, and proper exit signaling.

Incorrect lane choice, failure to yield, or excessive speed results in Grade 2-3 faults.
